T 0 all whom it may concern.-

Be it known that I, Ivonr HAZELTON, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Car-Gouplers, which will, in connection with the accompanying drawings, be hereinafter fully described, and spe cifically defined in the appended claims.

In said drawings, Figure 1 is a top plan View of a coupler embodying my invention. Fig. 2 is an elevation of the coupler shown in Fig. 1, taken as viewed from the bottom of the sheet. Fig. 3 is ahorizontal section taken as on line Z Z, Fig. 2, and viewed as from above that line. Fig. 4 is a side elevation viewed from the left in Fig. 1. Fig. 5 is a detached top plan view of the draw-bar and the detaching-cord.

My invention relates to that class of couplers which are more especially intended to be secured to the rear end of the tender, and by which the engine is coupled to the train of cars; and it consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring again to the drawings, A represents the frame of the coupler, which is preferably formed as an entire casting, and with a baseplate, I), through and by which it is rigidly bolted to the tender, and also having the two wings or flanges c c, which converge and unite at their upper portion, forming, with the raised portion of Z), the box-like part (3, that is covered by the foot-board g. In said raised portions (1 is arranged the buffer 6, which is cushioned by the helical spring f. Said parts thus farspecilied, being well known, need not be further described except in connection with the parts invented by me.

E represents the drawbar, having a head, 72, secured thereto by pivot t. Said bar extends throngh base-plate b, and is pivotally secured by bolt 7' to the V-like stay 0, which is secured to and extends from baselike plate I). Said base-plate b is cut away at Ya, Fig. 8, to allow a vibrating movement of' bar B upon its securingbolt j, it being habitually held in constant contact position, as there shown, by spring Z, secured in flange c of frame A,which spring is adjustable in its stress by means of screw or. A bar-like portion, a, of head h eX- tends into a slot in bar B, and at its end has a seat, 1), formed in it, to receive the correspondingly-formed detent s, which is habitually engaged therewith by helical spring t, the locking-lip g of part '12, being rounded away on its outer face to serve as a cam to force detent s inward against the stress of its spring when head It is being closed from the open position shown by dotted lines in Fig. 3.

For the purpose of detaching the coupler a cord, -o, is secured to detent s by means of stud u, said cord being carried to the cab, so as to be in convenient reach of the engineer and fireman, who, by drawing thereon, disconnect the detent from lip q, when the movement of the engine and tender will by the contact of head h with the coupler of the adjacent car swing the head into the position indicated by said dotted lines, thus freeing the engine and tender from the car, while the contact of the car-coupler with bar-like part it when the head it is swung open will close it to the position shown by solid lines in Fig. 3, thus coupling the engine and tender to the car.

As a precaution against the uncoupling of the tender and car when rounding very sharp curves, I providea locking-block, D, mounted to slide upon one of the wings c, as shown, and secured thereon by screw 10, passing through a slot in the block, so as to allow a free vertical movement thereof, which movement is effected by the engineer or fireman by means of cord 3, which extends into the cab, and is also attached to the vertical arm of hellcrauk x, that is pivoted at z to stud v secured to frame A, the opposite or horizontal arm of said lever being pivoted at 2 to said lockingblock D.

It will be obvious that, instead of retracting detent s by direct connection of cord 22 therewith, a lever may be interposed between it and said detent, whereby less force on the part of the operator will effect the same result, and draw-bar B may have an elastic instead of a rigid support, as shown, if preferred; and various other changes in the several details of construction may be made without departing from the spirit of my invention.

I claim as my invention- 1. The combination of draw-bar B, its latattached to the other arm of said lever, all erally-vibratingfie'ad h', formed'ivith seat 16, substantially 'as'spe'cified'f' and lip q, detent 8, spring t, and cord 1), all 3.
